I have had the same problem, using the same kind of setup, also using keyclone, but I don't think it's a keyclone problem. Here is my original post:

'Headless' macro not quite working how I would like, any thoughts?

The reason I don't think it's a keyclone problem is that I am not yet running my 5 man team on that powerful a computer, and I think it is something to do with that rather than anything else.
